compatibility with Bitcoin Core 0.15.0

Seeing as 0.15.0 is out (ok, tagged) I was wondering if/when it would be safe to upgrade. Looking at the draft release notes, changes are extensive and go deep, so I wouldn't expect something as closely integrated as Armory to just work as-is, so I thought we might have a thread about it.

Note that this isn't meant to rush anybody, it's done when it's done! Usually I'd wait a good while anyway, but I'd like to show support for Core by upgrading ASAP.

It should work out of the box, Armory does not care about Core's DB, just the block data on disk. If there's something that affects Armory, I'll look at it ASAP.
